The difference between top and bottom was nuts - a lot of people coming back down looked a bit miserable - probably the ones with no gear - 90 mins at -2 ain't gonna kill you but without gloves in that wind it wldn't be pleasant!
I only bought a couple of pairs as an afterthought! But at least we had them!
Yeah, -2 for extended periods isn't fun. It looks like a great walk though, I'd love to do it.
I can recommend it for sure just not peak season!
